Outokumpu delivers about 4,000 tonnes of LDX 2404 duplex stainless steel for the Husab uranium mine project in Namibia, Africa. Outokumpu stainless steel will be used in tanks, pressure vessels, clarifiers and columns. The deliveries have started and they will continue until September 2014.

The Husab Mine project is owned by Swakop Uranium and the project is led by Husab Project Joint Venture. Once completed, Husab will be one of the three largest uranium mines in the world.

Chris Tsai from Swakop’s majority shareholder China General Nuclear Power Corporation comments: “Leaching and counter current decantation processes as well as tanks fabricated at the site are one of the critical parts of the Husab project. Based on the excellent corrosion resistance, LDX 2404 has been chosen as the main construction material for the main body of tanks.”

“The Outokumpu LDX 2404 is the most suitable grade for this project due to its superior combination of corrosion and wear resistance and excellent mechanical properties. The wear resistance in particular is important, as the processed slurry contains high amounts of solid material. For the customer, LDX 2404 also gives clear benefits, such as lower overall cost. The grade enables thinner tank walls, requiring less material. Outokumpu delivers 2 meter wide stainless steel which results in less welding and fewer plates to manage. Furthermore, the expected lifecycle cost is low, since stainless steel requires very little maintenance,” says Johan Karlsson, General Manager of Outokumpu in South Africa.

FLSmidth is the engineering company that designed the first tanks for the Husab project. Pedro Miguel Teixeira from FLSmidth comments: “The cooperation with Outokumpu has worked well. Delivery was done on time and the quality of the product and service has been extremely professional.”

Michael van Kan from Husab Project Joint Venture says: “It was crucial for the project to select the right grade to ensure the optimal mix of strength and corrosion resistance for the process requirements. Outokumpu provided the Husab project with world class service from grade selection advice to technical support for the products. Husab Project Joint Venture will recommend Outokumpu for the supply of stainless steel because they offer a quality product with excellent service backup.”

Outokumpu is dedicated to good delivery accuracy which is very important in mining projects. In the Husab project, door-to-door deliveries from the mill to the fabricators were required. Outokumpu has this as a standard service in South Africa.

Outotec has been awarded two contracts for the management and execution of shut-down services of Samarco's four iron ore pellet plants in Brazil. These contracts, to be carried out together with Samarco's own personnel, will last until the end of 2016. The first year's services have been booked in Outotec's 2014 first quarter order intake.

Samarco has, in total, four pellet plants at its manufacturing facility in Ubú, in the state of Espírito Santo. Outotec has designed, supplied and installed the two newest indurating furnaces at the facility, both of which incorporate the use of Outotec core technology. The fourth indurating furnace, in the largest plant of its type in the world, was successfully commissioned in March 2014 and it is currently undergoing ramp-up of production with Outotec's operational support.

Outotec has already performed several big shut-down campaigns for Samarco. Over 250 workers have been involved in the last repair, which was finalized ahead of schedule with a zero accident rate.

"Samarco is a major producer of iron ore pellets and our long-term partner. The new service contracts are a further step towards a real life-cycle partnership between our companies. Acquired in 2012, Demil Manutenção Industrial in Guarapari played a significant role in this case. With the purchase, Outotec took over two on-going long-term maintenance contracts for Samarco's pelletizing and filtration areas. By combining our resources we can provide the full range of maintenance, shut-down and technical services for our customers", comments Kimmo Kontola, head of Outotec's Americas region."

The results for the customer include a safer working environment and improved process efficiency, leading to significant savings. Metso has won a significant repeat order for Neles® ball valves with Neles® Q-Trim noise attenuating technology from a North American pipeline owner that brings crude oil from Canada to US refineries.

By reducing cavitation, noise and related vibration to acceptable levels, Q-Trim technology protects process equipment, thus lowering the operating costs and minimizing the need for valve spare parts and other accessories. This, in turn, means lower total costs of ownership.

"The savings achieved for this customer with Metso's solution are estimated to amount to millions of dollars per year thanks to the higher efficiencies from our technology," says Kyle Rayhill, Global Business Manager, Neles & Mapag, Automation, Metso.

"It really pays off to deal with the noise problem even before it is created. Elevated control valve noise in the throttling process can be harmful not only to employees and surrounding communities, but it can also seriously damage process equipment. Once noise is created, it is hard to eliminate," Rayhill points out.

Based on the excellent achievements, this customer is increasing its installed base of Metso technology. The company has placed another order for more valves with Q-Trim in April 2014. Value of the order is not disclosed.

CALCULATING AND MITIGATING THE EFFECTS OF WATER HAMMER IN A LIQUID SAMPLING SYSTEM

By Dean Slejko, Product Manager, Analytical Products, Swagelok Company

In a liquid analytical sampling system, a common problem has the potential to destroy pressure gauges, flowmeters, pumps, and other sensitive components. It’s known as water hammer, and it occurs when a valve abruptly closes and liquid flow is suddenly stopped.

Water hammer strikes as a sudden pressure pulse that is in addition to the working pressure in a system. This pulse of additional pressure can be enough to damage every pressure gauge or flowmeter upstream of the closed valve. It can even burst lines or end connections if the pulse is too great.

Yet operators often don’t realize what caused the damage. They know the maximum process pressure won’t exceed the system’s design. So they have trouble understanding where the extra pressure originates.

Let’s take a closer look at why the phenomenon of water hammer occurs and how to estimate its effect in your sampling system. In addition, we’ll review a few methods for mitigating the water hammer effect, including using needle valves for shutoff, diverting flow instead of shutting it down, and using pressure snubbers to protect gauges.

Estimating Water Hammer

When the operation of a valve suddenly interrupts the flow of a liquid, something has to absorb the momentum of that liquid and bring it to a standstill. The liquid is heavy, and it’s travelling fast. Therefore, the force required to decelerate the liquid creates a rapid increase in pressure. This pressure surge originates in the compression of the liquid and from deformation of the tube walls. The resulting pressure wave travels upstream in the tube and, unfortunately, the pressure rises too quickly for a typical proportional relief valve to open and release it. Without a means of escape, the pressure spike can be severe enough to damage components anywhere in the line.

A variety of mitigation methods can help to avoid the sudden pressure spikes of water hammer. We’ll cover those methods in a moment.

But first, let’s review how to determine if water hammer may impact your sampling system. You’ll need to know a few specific details, including the density (ρ) and velocity (u) of your sample fluid. These parameters can be entered into an equation known as Joukowski’s Law, which estimates the magnitude of the water hammer pressure pulse (ΔP) experienced in a line when the liquid velocity (u) suddenly changes by Δu. The equation for Joukowski’s Law reads:

ΔP = c · ρ · Δu

The parameter c is the speed of sound in the liquid under actual operating conditions. For example, the speed of sound in water at 20°C is about 1400 m/s. Therefore, when the operation of a valve suddenly stops a water flow with a velocity of 1 m/s, the calculated pressure pulse is:

ΔP = 1400 m/s × 1000 kg/m³ × 1 m/s

ΔP = 1400 kPa

That’s 14 bar of additional pressure that you have likely not planned for in your sampling system. This extra pressure spike may not be tolerable for this particular system. And the pressure pulse will be even higher if the liquid sampling system flows at a higher velocity than 1 m/s.

In practice, the pulse pressure may not be as high as that calculated by the Joukowski’s Law equation. The full force of the pulse develops only when the change in velocity is sudden, specifically when Δu occurs within a given time period (t), as determined by the following equation (in which L is the length of the liquid line):

If the water line in the example above is 100 m long, then:

t ≥ 142 ms

The time period (t) is the time the pressure wave takes to spread along the upstream line and reflect back to the valve. The full pressure pulse develops only when the reflected pressure wave returns to find a closed valve. The above result indicates that the pulse will be less than the calculated pressure if the valve takes longer than 142 ms to shut off. In other words, you can minimize the water hammer pulse by closing the valve in more than 142 ms.

Mitigating Water Hammer

In domestic water systems, it’s common to mitigate water hammer by installing vertical pipes containing trapped air in water lines near each faucet. The air in the capped pipes absorbs the water hammer pulses. This design could work in sampling systems, too, but it would create an unacceptable dead leg that could lead to sample contamination. Instead, you’ll need to use other remedies to avoid water hammer.

First and foremost, don’t use ball valves to shut off the flow in a liquid sampling system. Ball valves shut off flow instantaneously, which can cause large pressure surges in the sample transport and conditioning systems.

Instead, you may opt to manage flow via one of two methods that help to mitigate water hammer issues, including:

1. Using multi-turn needle valves with tight shutoff seats to stop the flow, as shown in the fast-loop module in Figure 1. The needle valves isolate and bypass the fast-loop flow. They close the flow slowly, which dissipates the momentum over a longer duration and minimizes the water hammer pulse. Rising plug valves may also be effective.

2. Diverting the flow instead of stopping it. In Figure 2, a common handle operates two bypass valves, so they can’t move separately. The three-way ball valves have special porting that opens a bypass flow path before closing the main flow path. The valves are never off, so water hammer never occurs.

As noted earlier, pressure spikes due to water hammer are too fast for a pressure relief valve to open and relieve the excess pressure. The rupture disc in the pressure relief valve might burst, but it will do so too late to avert severe damage to an upstream flowmeter or pressure sensor. Those components will receive the full force of the water hammer spike before the relief valve opens.

Figure 1.

Figure 2.

Snubbing Pressure Pulses

Even by following the precautions noted above, valve operation in a liquid sampling system is likely to cause water hammer pressure pulses that may be large enough to damage pressure gauges. Your best defense is to use pressure snubbers to protect all gauges potentially exposed to the pressure pulses. A pressure snubber slows the response of a pressure gauge so it doesn’t respond to the transient pressure pulse in the line.

Protecting Your System

In summary, suddenly stopping flow in a sampling system can create a pressure surge that’s large enough to damage multiple components in the line. Known as water hammer, this surge is a system performance and maintenance issue, and could even be a safety issue if toxic system media were to escape due to a burst line or component. To mitigate water hammer, use needle valves to shut off sample lines, or divert the flow rather than shutting it down. In addition, consider pressure snubbers to protect pressure gauges in your system. These practices will help to minimize the effects of water hammer, reducing maintenance costs and system downtime, as well as enhancing safety.

One of the island of Tenerife’s leading experts on wind energy has delivered a speech at a sustainable energy conference at the RAC Club in Pall Mall on Friday May 2 2014.

The event, hosted by scientific field trip organisers GeoTenerife, brought a number of Tenerife’s leading scientists to London to share their efforts on making the island 100 percent renewable.

Guillermo Galvan, the Director of Wind Energy at the Tenerife Renewable Energy Institute (ITER), spoke about the science being learned from their neighbourhood of 24 fully bioclimatic houses.

Mr Galvan spoke of the challenges faced during the construction of the houses, and what lessons have been learned for use in future developments, particularly for sustainable tourism.

Speaking at the conference, Mr Galvan said “Sometimes you have to be innovative to integrate the bioclimatic design with an appealing house.

Our students and professors that visit Tenerife with us from architecture or sustainable backgrounds love to visit these houses

“This is of particular relevance to the type of sustainable tourism we are looking to develop in Tenerife.”

The ITER director was at the conference to highlight how these houses can help to advance Tenerife’s booming tourist trade in a sustainable fashion, as they have proved to be a runaway success with visitors to the island looking for chic and original properties.

Mr Galvan was just one of the scientists who attended the conference to demonstrate their work to potential British partners.

His speech was well-received by an attentive audience made up of representatives from UK-based renewable energy firms, delegates from African embassies and educationalists.

Sharon Backhouse, Director of GeoTenerife, says that the houses are extraordinary. Built in one of the most challenging environments on the island, beaten by strong winds and sun, the architects had to work hard to use only local elements to build houses that provided comfortable living conditions.

"Our students and professors that visit Tenerife with us from architecture or sustainable backgrounds love to visit these houses and see the various solutions proposed by architects from all over the world. Some of the houses are stunning, but not as effective bioclimatically. Some are semi buried, or use local stone to build series of walls and columns. One house even has plants on the roof, another has sea shells. And all of them are controlled electronically to see which performs best and why. It's the perfect bioclimatic laboratory."

Academic institutions interested in these houses and incorporating them into a detailed sustainable architecture field trip programme should contact GeoTenerife.

About GeoTenerife:

GeoTenerife is a British company that coordinates scientific bespoke trips to the island of Tenerife for UK Universities. It also organizes conferences and webinars on the island, bringing experts from Tenerife to the UK.

Our desire to promote the potential of the island is backed by over fifteen years of experience in the field of renewable energy. We work with investors interested in projects in Tenerife and schools of all levels in the UK.

Our events are specifically coordinated to the requirements of each group responding with activities tailored to their courses and levels of study.

Our goal is to redefine the island of Tenerife: not just a sun and beach destination, the island has resources and potential to be a key destination for global travel and scientific study of the highest level.
